Taro Router Hook

router hook for TaroJS

THIS HOOK IS PRE-PRODUCTION STAGE. USE AT YOUR OWN RISK

CAUTION 1

由于 Taro 的组件初始化和路由机制，首次渲染会返回默认值，请注意做好安全取值方案

routeState 的默认值为 {route: null, name: null, from: null, query: null, depth: 0}

Usage

import useRouter from 'taro-router-hook'

• name 简短的 pageName 默认值 null

• from 上一个页面的 pageName 默认值 null

• query 传入的路由参数对象 默认值 null

• depth 当前路由栈深度 默认值 0

router

路由方法集合

• push(pageName: string, query?: Object): Promise<any>

• redirect(pageName: string, query?: Object): Promise<any>

• pop(data?: Object, delta?: number = 1): Promise<any>

• popToRoot(): Promise<any>

Example

In PageA (src/pages/pageA/index.jsx)

import useRouter from 'taro-router-hook'

const PageA = () => {
  const [routeState, router] = useRouter()

  // 状态对象
  // routeState = {
  //   route: 'pages/pageA/index',
  //   name: 'pageA',
  //   query: {},
  //   from: null,
  //   depth: 1
  // }

  return (
    <View>
      <Button onClick={() => {
        const resp = await router.push('pageA', {hello: 'world'})
        // when PageB call pop, resp will be assigned with {foo: 'bar'}
        console.log(resp.foo) // => 'bar'
      }}>To PageB</Button>
    </View>
  )
}

In PageB (src/pages/pageB/index.jsx)

import useRouter from 'taro-router-hook'

const PageB = () => {
  const [routeState, router] = useRouter()

  // 状态对象
  // routeState = {
  //   route: 'pages/pageB/index',
  //   name: 'pageB',
  //   query: {hello: 'world'},
  //   from: pageA,
  //   depth: 2
  // }

  return (
    <View>
      <Button
        onClick={() => {
          router.pop({ foo: 'bar' })
        }}
      >
        Back
      </Button>
    </View>
  )
}
